Backed by the intensive R&D, Zenith products have attained international quality standards. The outstanding success of Zenith R&D rests on its unique development of rubber compounds meeting customer’s specific requirements :
  • Function, chemicals in contact.
  • Pressure exerted, working temperature and conditions
This is based on tests complying with international norms such as Oscillating Disc rheometer test and tests for tensile strength, abrasion and ageing etc. Zenith R&D department develops roller manufacturing equipment that is operator friendly, needs low maintenance and generates high performance at low production costs. Zenith has fully equipped laboratory with highly trained and experienced rubber technologists and engineers.
Zenith Laboratory is equipped with the following testing equipments :
  • Mooney Viscometer
  • Rheometer (ODR or MDR)
  • Tensile Tester
  • Abrasion Tester (DIN / Du Pont Abrader)
  • Resilience Tester (Vertical / Swing Drop Method)
  • Shore A/IRHD Hardness Tester with Holder
  • Compression Set Apparatus

A Compound is mixture of various ingredients with its base polymer to obtain the required physical and chemical properties according to industry specifications.

Zenith develops consistent, high standard rubber compounds to meet stringent requirement for roller manufactures for all industries. Zenith also delivers custom mixed compounds. Zenith only uses top quality raw materials. Our vendors/suppliers are required to furnish us with the material certification on every rubber ingredient. Zenith’s custom and advanced mixing facilities include kneader mixing, open mill mixing, straining and calendering that enable Zenith to offer the highest quality standards in its compounds.

Zenith’s technical facilities include state-of-the-art testing equipment and machines that are regularly maintained and calibrated. This enables Zenith to perform different tests and inspections right from raw materials to final product. These tests are for hardness, tensile strength, tear strength, abrasion resistance, fluid resistance, ozone/UV resistance, resilience and ageing among others.

All tests are carried out according to internationally accepted standards and/or the customer’s requirements by qualified and experienced personnel.

After extensive research, Zenith has developed various compounds for hardness ranging from 12 Shore A to 100 Shore A using a wide range of materials such as: NR, SBR, EPDM, NBR, PVC-NBR, CR, CSM, SILICONE (Q) and PU.

Zenith qualified and experienced staff can develop formulations and colour matching for specific requirements. Our extensive formulae library is constantly enhanced to keep pace with the rapid technological development.
